The containment apparatus 100 is configured to be removably attached to chair and table assemblies having various shapes and sizes. For example, when attached to a highchair assembly such as highchair assembly 102, the flexible barrier 108 and the adjustable coupler bend about highchair assembly 102 in order to accommodate its contours. The containment apparatus 100 may be configured for containing items on a tray such as, for example, toys, books, utensils, educational materials, therapy materials, combinations thereof, or any other items that may be placed on a tray.

With reference to FIG. 3. The flexible barrier 108 has an upper edge 110, a lower edge 112 opposite the upper edge 110, a first side edge 114, and a second side edge 116 opposite the first side edge 114. The lower edge 112 extends along a bottommost edge of the flexible barrier 108 and the upper edge 110 extends around an uppermost edge of the flexible barrier 108. The lower edge 112 may be configured to engage and attach to an edge or perimeter 118 of the tray 106. To secure the flexible barrier 108 to the tray 106, a portion of the flexible barrier 108 engages the perimeter 118. Alternatively, the entire lower edge 112 may engage the perimeter 118. Alternatively still, only portions of the lower edge 112 may engage and attach to the perimeter 118.

The flexible barrier 108 includes a middle panel 120, a right side panel 122, and a left side panel 124. The middle panel 120, the right side panel 122, and the left side panel 124 may each be configured to extend approximately perpendicular to and along the perimeter 118 of the tray 106. The right side panel 122 may extend from the first side edge 114 toward the middle panel 120. The left side panel 124 may extend from the second side edge 116 toward the middle panel 120. The right side panel 122 and the left side panel 124 may each be foldably attached to a first attachment edge 120 a and a second attachment edge 120 b of the middle panel 120, respectively. The middle panel 120 being at least partially defined by the first attachment edge 120 a and the second attachment edge 120 b. In an aspect of this disclosure, the right side panel 122 may have a shape and size that is substantially the same as the left side panel 124.

An interior of the flexible barrier 108 may be reflective. For example, a person sitting in chair 104 with the flexible barrier 108 attached to the tray 106 could see a reflection when looking at the flexible barrier 108. Alternatively, the flexible barrier 108 may be clear or transparent such that a person could see through the flexible barrier 108. The barrier may be formed of a synthetic, glossy material so as to facilitate cleaning, though this is not a requirement.

In an alternative aspect, the flexible barrier 108 may also include a left connection portion 126 and a right connection portion 128. The left connection portion 126 may be positioned in between the left side panel 124 and the middle panel 120, and the right connection portion 128 may be positioned in between the right side panel 122 and the middle panel 120. The left connection portion 126 may be configured to foldably connect the left side panel 124 to the middle panel 120, and the right connection portion 128 may be configured to foldably connect the right side panel 122 to the middle panel 120.

The elastic material 136 may be configured to engage with the perimeter 118 of the tray 106 to which the containment apparatus 100 is secured. The elastic material 136 may be in the form of a skirt or other extension from the panel or panels. In some embodiments, the elastic material 136 acts to stretch and then secure at least a portion of the apparatus 100 to the tray 106. As one example, an elastic material 136 (e.g., Spandex™, Lycra™, or even material from a Spanx™ garment or similar) may be sewn to a bottom edge of the flexible barrier 108. When the apparatus 100 is deployed about a tray 106, the elastic material 136 is then stretched around an edge of the tray 106 so as to secure the apparatus 100 to the tray 106.

The left and right connection portions 126 and 128 may comprise a stretchable or flexible material, such as, for example, rubber, neoprene, spandex, or the like. The flexible material may enable the flexible barrier 108 to extend or stretch around the tray 106 to provide a secure connection. The flexible material may also enable the flexible barrier to extend around trays 106 having a variety of shapes and/or sizes. The apparatus 100 may exhibit a curved profile when deployed in a planar state atop a flat surface.
